I'm feeling disagreeable so here goes:
I think the narrative that "Silicon Valley broke its own bank and it's another example of how tech is broken" is complete hokum, and exonerates the actual villains here.
Bank runs happen all the time.
They are what happen when you have insufficient bank regulation.
The bipartisan bill of 2018 that let SVB dodge good banking rules is the actual problem here.
This is not a tech issue, it's a banking one.
